Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The large hole in the occipital bone through which the spinal cord exits the skull.






2. A joint that allows only a rotary motion; the only true joint of this type is the atlantoaxial joint ('no joint').






3. The kneecap; the largest sesamoid bone in the body; located on the front surface of the stifle joint in the tendon of the large quadriceps femoris muscle. It rides in the trochlea of the femur.






4. The last - most caudal sternebra; the _____ process.






5. Skull bones that are part of the external bones of the face; form the bridge of the nose or the dorsal part of the nasal cavity.






6. Long bones of the axial skeleton that form the lateral walls of the thorax; dorsal portions are made of bone and form synovial joints with the thoracic vertebrae. Ventral portions are cartilage.






7. The bony roof of the mouth; the division between the mouth and the nasal cavity. Made up of portions of the maxillary and palatine bones.






8. The vestigial metacarpal and metatarsal bones of a horse's leg. There are two spint bones in each leg: one on either side of the cannon bone (MC/MT III). The medial bone is MC/MT II and the lateral bone is MC/MT IV.






9. Small bones shaped like cubes or marshmallows; an example are the carpal bones.






10. The second cervical vertebra; it forms the atlantoaxial joint with the first cervical vertebra - the atlas.






11. The hormone secreted by the parathyroid gland that prevents the level of calcium in the blood from getting too low.






12. The end of a long bone; each long bone has a proximal and distal _____.






13. The visceral bone in the snout of swine that strengthens it for the rooting behavior of pigs.






14. The fibrous membrane that covers the outsides of bones except for their articular surfaces.






15. The long bone of the thigh region; it forms the hip joint with the pelvis at its proximal end and the stifle joint with the tibia at its distal end.






16. An alternate name for joint cavity.






17. The process of a vertebra that forms a synovial joint with an adjacent vertebra.






18. Skull bones that are part of the internal bones of the face; make up the caudal portion of the hard palate.






19. The socket portion of the ball - and - socket hip joint; it is formed at the junction of the ilium - ischium - and pubic bones of the pelvis.






20. The healing tissue between the ends of a fractured bone that is eventually replaced by true bone as the fracture heals.






21. Small cavities within the matrix of some connective tissues - such as cartilage and bone - within which cells are contained.






22. The vertical portion of the mandible located at its caudal end; site where jaw muscles attach to the mandible.






23. A gliding joint in which two flat - articular surfaces rock on each other; this type of joint usually allows only the movements of flexion and extension.






24. The bones along the central axis of the body; made up of the skull - hyoid bone - the spinal column - the ribs - and the sternum.






25. An arthrodial joint in which two flat articular surfaces rock on each other; the carpus is an example.






26. Also known as the spinal column; the collective name for the cervical - thoracic - lumbar - sacral - and coccygeal vertebrae.






27. Bones that are longer than they are wide; most of the limb bones are in this category.






28. A joint movement that consists of a twisting motion of a part on its own axis.






29. The central canal that runs the length of a haversian system; contains blood vessels - lymph vessels - and nerves that supply and nourish the osteocytes.






30. A hole in the bone.






31. The paranasal sinus in the maxillary bones.






32. Paired sesamoid bones in the legs of horses; located in the large digital flexor tendons behind the fetlock joints.






33. The membrane that encloses the ends of the bones in a synovial joint; consists of an outer fibrous membrane and an inner synovial membrane that produces viscous synovial fluid that lubricates the joint surfaces.






34. Another name for a pivot joint; one bone pivots on another in a rotary motion. The only true pivot joint is the atlantoaxial joint.






35. Another name for cancellous bone.






36. Skull bones that are the bones of the ear; three pair of bones in the middle ear that transmit sound wave vibrations from the tympanic membrane to the inner ear.






37. The hind limb.






38. A toe made up of two or three boens called phalanges.






39. A joint whereby one surface swivels around another like a door hinge; also called a ginglymus joint. The only movements possible are flexion and extension; the elbow is an example.






40. The group of vertebrae located dorsal to the abdominal region.






41. Skull bones that are part of the external bones of the face; these two bones are the most rostral skull bones and contain the upper incisors in all domestic animals except ruminants.






42. The long - flexible - caudal portion of the dorsal body cavity formed by the adjacent arches of the vertebrae of the spine; it houses and protects the spinal cord.






43. A lateral - projecting process of a vertebra.






44. The process on the distal end of the distal phalanx of dogs and cats that is surrounded by the claw in the living animal.






45. The shoulder blade; the most proximal bone of the thoracic limb. No bony connection exists between the scapula and the axial skeleton.






46. The bones of the limbs (appendages)






47. The cartilaginous joint (amphiarthrosis) that unites the two sides of the mandible at the rostral end in dogs - cats - and cattle.






48. The outer layer of a bone that is composed of compact bone.






49. A toe that does not reach the ground - such as the first digit of dogs and cats and the rudimentary medial and lateral toes of cattle.






50. The bones of the pelvic limbs located between the tarsus and the phalanges.
